Dear all,
I want to calculate ab initio, the Hubbard U, used in the LSDA+U calculations.
The linear response method mentioned in the Cococcioni et al.'s paper seems to
be a non-standard method for QE. I mean specially the application of localized
perturbation (Delta V) needs some thing to be done by other tools. So my
question is that is there any other method of U calculation (non-LR) already
examined with QE or is using the traditional LR method much simpler than what I
supposed it to be?
Thanks,
Ali
